Here's the deal: I have a soft-modded box running Evox, with XBMC installed. Before I modded the box, I had it set to 16:9 within the MS Dashboard, but now that I've modded it, the MS Dashboard is missing from the menu (it's typed in red, and unselectable). It wouldn't be a problem if it weren't for the fact that I switch my xbox from a widescreen TV to a 4:3 one pretty regularly.
Now, for watching videos XBMC works fine for switching between these two modes, so that's not the problem. The problem, however, lies in running games, which don't run according to XBMC's settings, but according to whatever it was that the MS Dashboard changed (probably in the bios), meaning that 16:9 enabled games look wrong on a 4:3 screen.
So my question is: Is there any chance for me to switch back to 4:3 without reinstalling MS Dash? Or is there something I'm missing?
